Why revenue sharing is completely effaced in Techulator?

With my observation, I've got to know that most of the spider sites are still having the wonderful program called "Revenue Share Bonus". But why it was taken away from Techulator? It was such an excellent program which motivates the members to contribute more and more. I personally request the webmaster to reinstate the same. So that the members would relish a lot and do their best.

As I have observed, TEC has also increased the cash credits for posting answers in Ask Experts section. And cash credits for writing resources have also become better. So, the Revenue Share bonus has been discontinued.
